If I use a good video editing tool to convert the movie source from 10bit to 8bit first, then encoded by x264, the problem goes away.
If I use ffmpeg to do the 10bit to 8 bit conversion, then encoded by x264, the blocky problem still exist but less severe.
Does x264 support 10bit to 8bit encoding? How to solve the blocky artifacts?
